Hm.. according to the original commit description "ON" / "OFF" is used to turn
the not-in-use-card on/off...
What was the behavior before v2.6.38-rc4? I don't know if this was an intended
change in behavior or an unintended side effect of some other change. Dave
Airlie can probably tell though...
p.s.:
Anyway, I presume working around that in userspace is not the issue? (i.e.
maybe doing something like this:
IGDINUSE=`grep IGD /sys/kernel/debug/vgaswitcheroo/switch | awk -F":" '{ $3 }'`
if [ "x$IGDINUSE" != "x+" ]; then
echo IGD > /sys/kernel/debug/vgaswitcheroo/switch
fi
)
